Definitions
- the present invention relates to an at least monoaxially oriented polypropylene film with improved antiblocking behavior.
- Polypropylene films are widely used as packaging materials. However, they are also used for film lamination in the graphics industry, as they have advantageous physical properties. Problems can arise on high-speed packaging and / or processing machines. It is therefore already known to use antistatic agents, lubricants and in particular blocking agents to improve the corresponding properties.
- Finely divided silicon dioxide is widely used as an antiblocking agent, see EP-A-27 586 and EP-A-189 242. It is known from EP-A-242 055 to use a non-melting cross-linked silicone to improve the antiblocking properties. According to DE-A-2 244 703, an improvement in the sliding properties of polypropylene films is to be achieved by using thermoplastic polymers such as polyamide 6, polyamide 6,6, polyethylene terephthalate or polyethylene oxibenzoate. According to Japanese Laid-Open Patent Sho 45-29 056, improved antiblocking properties with good transparency are to be obtained by using polymethyl methacrylate and / or polystyrene.
- the object of the present invention was therefore to provide an improved film.
- the present invention relates to an at least monoaxially stretched polypropylene film, each containing at least one lubricant, one antistatic and one antiblocking agent, characterized in that the antiblocking agent contains polymerized isobutyl methacrylate and methyl methacrylate.
- the film is a transparent film.
- the antiblocking agent according to the invention is preferably a copolymer or a mixture of polymerized isobutyl methacrylate and methyl methacrylate.
- the antiblocking agent is preferably crosslinked.
- the molar ratio of isobutyl polymethacrylic acid and methyl polymethacrylic acid generally ranges from 1.2: 1 to 7.0: 1, preferably from 1.2: 1 to 4.5: 1, especially from 1.9: 1 to 3.1: 1.
- Such polymers can be obtained in a known manner by polymerizing the starting components.
- the antiblocking agent to be used according to the invention has predominantly spherical or elipsoidal form, in particular with an average particle size of 0.5 to 7 »m, in particular 0.7 to 4» m.
- FIG. 1 shows a microscopic picture of such an antiblocking agent.
- the shape factor of an individual particle of the antiblocking agent according to the invention is preferably in the range of 0.9 ⁇ f ⁇ 1.
- the antiblocking agent to be used according to the invention is preferably contained in the polypropylene film in an amount of 700 to 5000, in particular 1500 to 2400 ppm.
- the films according to the invention can have one or more layers, with the outer layers always containing the additive according to the invention in the case of a multilayer.
- Preferred outer layers are sealing or lamination layers.
- Preferred compositions for the outer layers are polypropylene homopolymers or copolymers of propylene with ethylene or propylene with butene or ethylene and butene, the proportion of polypropylene generally being at least 70% by weight.
- A is preferred for the polypropylene of the core and outer layers Isotactic polypropylene with a density of 0.9 to 0.91 g / cm3 and a melt flow index of 1 to 4 g / 10 min at 230 ° C / 21.5 N (according to DIN 53 735) was used.
- the base layer can e.g. Contain 3 to 15 wt .-%, preferably 8 to 12 wt .-% additives incompatible with the polypropylene, preferably inorganic additives such as calcium carbonate, silicon dioxide, sodium aluminum silicate and / or titanium dioxide, whereby an opacification of the film can be achieved.
- inorganic additives such as calcium carbonate, silicon dioxide, sodium aluminum silicate and / or titanium dioxide
- an organic, incompatible additive can also be present in the base layer in finely divided form, preferably particles of polystyrene, polymethyl methacrylate, polytetrafluoroethylene, polycarbonate and / or copolymers of these compounds.
- Incompatibility means that such polymeric additives have a different melting point and / or a different stretching ratio than the polypropylene, so that under suitable conditions in the biaxial orientation process of the multilayer film, the polymer matrix is torn open and thus a vacuole is formed, which also occurs when inorganic additives are used occurs. This can cause the film to become opaque.
- the films have a heat seal layer known per se, in particular copolymers of propylene.
- the multilayer films can also be a gas barrier layer, preferably an oxygen barrier layer made of a saponified ethylene / vinyl acetate copolymer with 40 to 85 mol% of vinyl acetate units, which are saponified at least to 90% by weight, preferably to more than 96% by weight optionally contain conventional adhesive layers.
- a gas barrier layer preferably an oxygen barrier layer made of a saponified ethylene / vinyl acetate copolymer with 40 to 85 mol% of vinyl acetate units, which are saponified at least to 90% by weight, preferably to more than 96% by weight optionally contain conventional adhesive layers.
- the production of such ethylene / vinyl alcohol copolymers is known.
- the present invention therefore also relates to heat-sealable multilayer films which have low gas permeability and excellent aroma protection.
- the multilayer films treated according to the invention can carry a thermal lamination layer made of low-sealing polymers on one side. By applying heat and under pressure, such a film can initially against other substrates are hot-laminated and then in love with the page pretreated according to the invention and printed.
- Preferred antistatic agents are alkali alkane sulfonates, polyether-modified, that is, ethoxylated and / or propoxylated polydiorganosiloxanes (polydialkylsiloxanes, polyalkylphenylsiloxanes and the like) and / or the essentially straight-chain and saturated aliphatic, tertiary amines with an aliphatic radical with 10 to 20 carbon atoms Hydroxyalkyl- (C1-C4) groups are substituted, including N, N-bis- (2-hydroxyethyl) alkylamines with C10-C20, preferably C12-C18 are particularly suitable as alkyl groups.
- the effective amount of antistatic is in the range from 0.05 to 3% by weight, based on the layer. If polyether-modified polysiloxane is used, this is added only to the polymer for the base layer and / or the polymer of those of the two sealing layers which is provided as a polydialkylsiloxane-incorporated layer
- Suitable further antiblocking agents are inorganic additives such as silicon dioxide, calcium carbonate, magnesium silicate, aluminum silicate, calcium phosphate and the like, nonionic surfactants, anionic surfactants and / or incompatible organic polymers, such as polyamides, polyesters, polycarbonates and the like.
- lubricants are higher aliphatic acid amides, higher aliphatic acid esters, waxes and metal soaps.
- the effective amount of lubricant is in the range of 0.1 to 2% by weight based on the layer.
- the usual stabilizing compounds for ethylene, propylene and other ⁇ -olefin polymers can be used as stabilizers.
- the effective amount is generally 0.1 to 2% by weight, based on the layer
- the films can be produced by conventional methods such as lamination, coating or melt (co) extrusion.
- the films are stretched at least monoaxially, preferably biaxially.
- the longitudinal stretching is preferably carried out in a ratio of 5: 1 to 7: 1 and the transverse stretching in a ratio of 7: 1 to 10: 1.
- the polypropylene film preferably has a thickness of 10 to 50 »m.
- the film according to the invention can be pretreated on one or both sides in the usual way, in particular with a corona, fluorine or plasma pretreatment.
- the film has a hot lamination layer on at least one side, in particular from an ethylene-vinyl acetate copolymer and a further copolymer, selected from the group consisting of ethylene methyl acrylate and ethylene-acrylic acid copolymer.
- a hot-laminatable layer is understood here to mean a layer which, owing to its relatively large thickness, is suitable for connecting the film to other substrates such as paper or cardboard, and for processing such compounds as brochure and book covers, record sleeves and cardboard packaging.
- the films according to the invention are particularly suitable for processing on high-speed packaging machines. It also enables processing on drum and tunnel laminating machines at high speeds
- the films produced according to the invention are suitable for film lamination, in particular glossy film lamination, graphic products such as book covers, brochure covers, book covers, record covers, packaging, etc.
- the antiblocking agent to be used according to the invention is preferably used only in the outer layers.
- test specification DIN 53 375 determination of the friction behavior is used to assess the sliding properties of films.
- the friction measurement according to this regulation is used to determine the behavior of foils when two foils rub against each other and the friction of a foil against metal.
- the coefficient of friction is given Liste
- optical properties are assessed by light microscopy with magnifications 50: 1 to 150: 1 of the vacuoles formed around the antiblocking agents during the stretching process
- the turbidity is measured in accordance with ASTM D 1003. Deviating from the test specification, the film sample is positioned in such a way that scattering angles ⁇ 8 ° are also measured and thus larger contaminants can also be determined.
- a film is made of polypropylene with a density of 0.91 g / cm3 and a melt index of 3.3 g / 10 min (230 ° C / 21.6 N). The film is first 4.7- to 5- stretched lengthways and then 9.2 to 9.8 times. The film thickness is 15 »m. The film is corona-pretreated on both sides
- the film contains the following additive components: 0.1% by weight of an additive consisting of isobutyl polymethacrylic acid and methyl polymethacrylic acid in a molar ratio of 2.5: 1 0.15% by weight of an ethoxylated amine as an antistatic 0.3% by weight of an erucic acid amide as a lubricant
